Excel 2007 or 2010 is much easier to use. If you don't have it you can download it from some file sharing sites.

Quick way to do this with a formula in any version of excel: if the data is in column A then first sort the column, then in cell B1 put the formula =EXACT(A1:A2) and copy the formula to the end of the data. You can remove data that is TRUE in column B.

I'm assuming that since you have Microsoft Excel, you have (or can get) Microsoft Access. Import the files into an Access MDB. Create a new query, and go to the SQL view... SELECT DISTINCT FIELD1 ,FIELD2 ,FIELD3 ,.and so on FROM yourtablename The result will be a de-duplicated version of the original table. "SELECT DISTINCT" is ANSI SQL, so it will also work in MySQL, SQL Server Express, or any other flavor of SQL you might have or any product that has a SQL interpreter (FoxPro, etc.).
